Costway Mini Split Review — Budget-Friendly Comfort That Gets the Job Done

Overview

COSTWAY’s 12,000 BTU wall-mounted mini split targets value-minded buyers who still want inverter efficiency. It’s a good match for apartments, secondary suites, or smaller homes where cost and simplicity matter.

Performance & Installation

Cooling performance is strong for mid-sized rooms and light open-concept areas. Heating is serviceable for shoulder seasons and mild winters, though output tapers in sub-zero temperatures compared with cold-climate units.
The included install kit helps keep costs down, but most homeowners should still hire a licensed HVAC pro to evacuate the lines and confirm charge. DIY is possible for experienced users, yet professional commissioning reduces the risk of leaks and noise issues.

Energy Efficiency

Depending on the exact variant (115 V vs. 208/230 V), SEER2 ratings typically land ~20–24, respectable at this price and noticeably more efficient than old window A/Cs or fixed-speed systems.

Noise & Controls

Noise levels are comfortable for living spaces; the outdoor unit is modest in cooling and moderate under heating load. Controls are straightforward; some models include basic Wi-Fi, but advanced smart scheduling is limited.

Pros

• Attractive price for a full inverter mini split

• Decent efficiency (SEER2 ~20–24 depending on model)

• Install kit included lowers total project cost

• Good cooling for bedrooms and mid-size living rooms

Cons

• Not optimized for harsh, prolonged sub-zero heating

• Smart features are basic versus premium brands

Final Verdict

A sensible, affordable upgrade if you need efficient cooling plus supplemental heat. COSTWAY delivers a lot of value for homes in milder regions or for rooms that don’t need deep-winter heating performance.
